192 HEMIPTERA-HETEROPTERA. 
NEONINUS, n. gen. 
Closely allied to Ninus, but differs by having the first joint of the antenne distinctly 
passing the apex of the head, and the second joint much longer than the fourth, which 
is subequal in length to the third; the fourth joint is also strongly incrassated. ‘The 
head is more elongate, the eyes less prominently exserted, and the pronotum more 
elongate and narrowed anteriorly than in Stal’s genus. 
1. Neoninus illustris, n.sp. (Tab. XIX. fig. 5.) 
Head, pronotum, scutellum, clavus, and base of corium dark fuscous, thickly clothed with pale greyish 
pubescence., Head coarsely punctate; ocelli prominent and black; antenne with the first and fourth 
joints dark castaneous, the second and third pale luteous, first shortest and globosely incrassated, second 
longest and longer than fourth, apical joint much thickened. Pronotum coarsely punctate, with a central 
pale longitudinal line, less pubescent and more fuscous posteriorly, and with two pale, transverse and 
waved fascie, situated a little before anterior margin. Scutellum coarsely punctate, with the basal angles 
and a central longitudinal line pale greyish. Clavus with the usual series of punctures, and with the 
apex broadly dark fuscous. Corium pale luteous hyaline, with the basal angle greyish pubescent, beyond 
which it is slightly dark fuscous, apical angles fuscous. Membrane pale hyaline. Abdomen above 
greenish. Head beneath and sternum fuscous, clothed with greyish pubescence and coarsely punctate. 
Rostrum ochraceous, the base fuscous (apex mutilated). Femora castaneous; tibise and tarsi pale 
ochraceous, the last with the apical joint pitchy. 
Long. 4 millim. 
Hab. Guatemata, Torola, Chiacam (Champion). 
An apparently rubbed specimen, sent by Mr. Champion from Chiacam, has lost 
the greyish pubescence, thus exhibiting the head, pronotum, scutellum, and clavus 
dark fuscous. 7 
ISCHNORHYNCHUS. 
Cymus, subg. Lyctus, Flor, Rh. Livl. i. pp. 287 & 294 (1860). 
Ischnorhynchus, Fieb. Kur. Hem. pp. 51 & 199 (1861) ; Stal, Ofv. Vet.-Ak. Férh. 29. 7, p. 44 
(1872) ; En. Hem. iv. p. 123 (1874). 
This genus may be known by the apex of the corium passing the apex of the 
abdomen, a character which will separate it from the only other American genus at 
present described. The body is oval; and the apical margin of the corium and claval 
suture are of nearly equal length. 
This genus is represented in the Palearctic, Nearctic, and Neotropical Regions. 
There are at present but few described species; but as these are small and obscure, 
and therefore at present little known from the labours of the average collector, [schno- 
rhynchus may probably have a much wider range and possess many more species. 
Dr. Puton has proposed the substitution of the name Kleidocerus, Westw., for this 
genus; but Mr. Douglas Has argued (Ent. Mo. Mag. xv. p. 235) that Kleidocerus 
“ being merely a name, it cannot supersede Ischnorhynchus, which is a genus duly 
defined by Fieber.” ,
